I have a question regarding a project I'm working on. I have 30 squares in one scene and all squares are numbered from 1 to 30. The numbers are also in random order. What I want too achieve is that you can click on any number you want and it will go to a specific scene/slide. For exsample when I click the number 12, it wil show a picture. But when you go back to the main scene, but number 12 should not be clickable any more. So you can't click on a number ones you've already clicked it.
Can anybody tell/show me how too achieve something like this?
